IMPLEMENT-HOLDER TILLING-MACHINES.

I Specification of Letters Patent.

Patented Mar. 2, 1915.

original appIication filed June 17, 1912, Serial No. 704,037. Divided and. this application filed December 4,1912. Seria1No.734,834.

To all whom it may concern Be it known that I, WILLIAM C. ZELLE, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in-Implement-Holders for Tilling-Machines, of which the following is a specification.

This invention relates to implement holders for tilling machines, and its subject-matter is divided out of an application for Letters Patent of the United States, for a tilling machine, dled by me on June 17, 1912, Serial Number 7 04,037

The invention has for its principal objects to provide for the attachment to a carrier implements or tools of various kinds interchangeably; to provide for adjusting the implements to various heights, and for setting them at different angles or working positions; and to attain certain advantages which will hereinafter more fully appear.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings which form part of this specification and wherein like symbols refer to like parts wherever they occur,Figure 1 is a fragmentary top plan view of an implement carrier with an adjustable implement holder thereon, illustrating an embodiment of the invention; Fi 2 is a side elevation; Fig. 3 is a section on the line 3-3 of Fig. 1; Fig. 4 is a section.

on the line 4-4 of Fig. 1; Fig. 5 is a section on the lines 55 of Figs. 1 and 4; and Fig. 6 is a section on the lines 66 of Figs. 1 and 4.

The device illustrated in the drawings is designed moreparticularly to be used in connection with the kind of carrier or drag set forth and claimed in said application Serial Number 7 04,037 of which this application is a division, but it is obvious that the device may be modified so suit other structures. Only so much of the carrier or drag frame is shown as is necessary to a full un derstanding of the present invention.

Generally stated, the carrier or drag comprises a frame hinged to a supporting device which is movably mounted on a tractor or vehicle and arranged and adapted so that the carrier or drag may be raised and lowered without disturbing the particular working position for which it is set. The tractor and supporting device are set out with particularity and claimed in applications Serial Number 687,929, filed April 1, 1912, and Serial Number 704,036, filed June 17, 1912.

The carrier or drag comprises transverse channel'members 37 which are arranged in spaced pairs with their webs vertical and flanges disposed outward. These channel members have their middle portions riveted to a strut member 39. The end portions of said channel members are riveted to yokes or brackets not shown, but which may be pivoted to the drag frame so that said carrier members may be rocked and set at various angular positions as set out with more particularity in said application Serial N umber 7 04,037 Channel members 40 are fitted slidably over the channel members 37, and the flanges of both the members 37 and the members 40 are provided with a multiplicity of perforations 41 adapted to register so as to receive locking pins as will pres ently appear. The channel members 37 and 40 have their flanges extended laterally, the former at their outer ends and the latter at their inner ends, and riveted to said 6Xil6Ilsions are oppositely disposed substantially U-shape clips '42 in which right and left hand double screws 43 are swiveled. The screws have collars 44 located between the clips provided with polygonal faces for the reception of a wrench. Locking members 45 have shank portions 45 threaded on the screws 43.- They also have pins 46 adapted to work in square notches in the flanges of Y the channel members in order to hold them from turning; while inwardly from said square portions they are rounded in order to permit them to turn after the square portions are moved clear of said notches.

By rotating the screws 43 the locking members 45 are drawn toward each other to bring the projections 46 into the perforations 41 and thereby lock the sliding channel members with respect to the fixed ones. The implement carrier or drag thus comprises a rigid frame having extensible transverse members on which individual holders for the implements to be presently described are adj ustably and interchangeably mounted.

The middle strut member 39 is provided with a central vertical opening e9 through which the shank of an implement may be passed. This opening 49 is preferably made to correspond with the contour of a shank 50 having flattened opposite faces whereby the shank is permitted endwise movement but is prevented from rotating'therein. The strut member is provided with a circular recess 51 having tapered side walls adapted to receive a nut 52 having a beveled flanged end portion-52" which is a counterpart of :the recessed portion of the strut. Aisecuring plate53 having a central opening in which thecircular-middle portion 52 of the nut fits is secured on top of the strut toihold the nut inplace. The proj ecting-upper portion 54lof the nut .is providedwith polyg- ,onal faces-fer the reception of a suitable wrench. The shank 501 is screw-threaded for aportion ofitszlength tofit the nut by the rotation ofwhich latter in itsseat said shank is raised and lowered.

Ad ustable implement holders comprising substantially rectangular, frame-like members 55 having seat portions -5 on oppositesides which are counterparts of the channel members are adapted to be detachably securedto, the shdable'channel members 40. These inplement holders are provided with pivoted dogs 56 having pins or projections 57 adapted to, enter the perforations 41in the channel members so as to' hold: said holders in place. -The dogs 56 are provided with :screws 58 adapted to bear against the top of the holder frame so that said dogs may: be held with their pins =57 in the, respective perforations of the I channel 1 members.

' The holder frame members have rocking members swiveled therein, the aXis of the trunnions' 59 ofsaid rocking members beng atri 'ht angles to the channel members .37 and 40. The rocking member-59 is provided with asector 60 adapted to cooperate withv a ,worm screw 61 journaledin brackets a plate 66 having a central-opening inwhich the middle portion of the -nut isrotatably fitted. -The plate 66' is rectangular andis .securedflby cap screws 66 to the rocking member 59. The upperportion 67' of-the nut is provided with polygonal faces for the reception of a wrench. The rocking member 59 is provided with a pairbfhalf widths.

journal brackets 68 with which similar brackets 69 on the plate 66 cooperate. Journaled in these hearings is a worm screw 70 w 1lCl1 meshes with a worm wheel 71 on the swivele-d shank holder 64: whereby the latter may be rotated. This worm screw is also provided with polygonal faces 70 to receive a wrench.

.By adjusting the channel members e0 with respect to the channel members 37 the implement carrier or drag frame may be extended or contracted to different The implement holders, with the exception of the onemounted on the middle strut member, mayalso be placed at any desirable position lengthwise of the channel members, and theimplements set at various angles, The implement holder atthe middle of the frame is, however, capable of vertical adjustment. This adjustment is all that is necessary as the middle implement always travels along the middle-ofa furrow in a neutral position. It is-diiferent, however, with respect to the other implements on either side of the middle one, as they have to beset at various anglesinorder to throw the dirt toward or away-from the middle of the furrow, depending upon the nature of treatment.

Various combinations maybe arranged by adjusting the implement holders on a carrier or. drag frame. "F or example, in barring-off a-plow may be mounted at either. side of the holder frame so that the soil is only treated adjacent-to the plants at the topsof the'furrows without touching the middles. In another-case a double mold board'may 'be mounted at the middle of the frame andon either side thereof may be arranged right and'l'eft hand plows for throwing a little dirt to the plants on opposite sides of :the furrow, and at the same timestirring the soil-to kill the grass and weeds. Then, again, thesoil'may be stirred with shovelbladeswhich may bearranged transversely to the direction of travel, in

-whichcase they do not throwearth to the plant, norfromit. Obviously, however, the shovels may be set so that the soil-can be throwntowardor from the plant, as desired. Also, in laying-by, the dirt maybe started at the middle of the furrow witha double mold board p-low, then' throwing it closer to the plants by right and'left' hand mold board plows,-and, finally, throwing the soil into the plant with sets of' disks. So, too, the entire furrow-may becultivated with disks. 'There maybe a set of disks arranged to throw-the dirt away from the plant at the top of 'the'furrow, followed by a set of disks tlnowing the "dirt from the middle toward the plants and these followed by other sets ofdisks picking-up the dirt and throwing'it still'nearer the plants, and, finally, sets of disks throwing the dirt into the plants. These and any other desirable combinations may be effected owing to the universal adjustment of the device.

The rocking members 59 are provided with arcuate scales 59 on their side faces in cooperate relation to indicator marks 59 on the adjacent top face of the implement holder frame while the rotary shank holder 64: has about'its upper peripheral portion, preferably on the upper'ends of the teeth of the worm gear 71, a series of graduations G lwhich maybe arranged in two series on opposite sides, or, obviously, as a continuous annular series'entirely girdling the member. These graduations 64 are used in connection with indicator marks 6t on the plate 66 which holds the nut and shank holder 64 on the rocking member 59.

Obviously, the device admits of considerable modification without departing from the invention. Therefore, I do not wish to be limited to the specific construction and arrangement shown.
